Waldron on Isaiah Berlin & Enlightenment Constitutionalism

One of the most important achievements of the Enlightenment is what I shall call Enlightenment constitutionalism. It transformed our political thinking out of all recognition; it left, as its legacy, not just the repudiation of monarchy and nobility in France in the 1790s but the unprecedented achievement of the framing, ratification, and establishment of the Constitution of the United States. It comprised the work of Diderot, Kant, Locke, Madison, Montesquieu, Rousseau, Sieyes, and Voltaire. It established the idea of a constitution as an intricate mechanism designed to house the untidiness and pluralism of human politics.

Yet Isaiah Berlin, supposedly one of our greatest interpreters of the Enlightenment, said almost nothing about it. The paper develops this claim and it speculates as to why this might be so. Certainly one result of Berlin's sidelining of Enlightenment constitutionalism is to lend spurious credibility to his well-known claim that Enlightenment social design was perfectionist, monastic, and potentially totalitarian. By ignoring Enlightenment constitutionalism, Berlin implicitly directed us away from precisely the body of work that might have refuted this view of Enlightenment social design.
